Lookup label: Q070104
Drawing use: SLD, Schematic
Reference families: IEC, Manufacturer

## Symbol convention

Convention: IEC
Form: Switch-disconnector function qualifier
Autodesk IEC-60617 Symbol Preview — Operating-device and function qualifiers; vendor family reference, not certified IEC geometry or database identifier.

This qualifier identifies combined switching and isolation in the associated representation.

## What it represents

This qualifier identifies combined switching and isolation in the associated representation. The combined function tells the reader that switching and isolation belong to the associated device representation. It does not add an overcurrent trip function.
When the SLD is expanded into a control schematic, retain the device tag and show any auxiliary contacts or operating mechanism separately. Protective devices elsewhere in the circuit remain separate items.

## How to read it

- Read it with the complete power device and its operating-state information.
- Switch-disconnector duty is different from automatic circuit-breaker interruption.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Read it with the complete power device and its operating-state information.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

Switch-disconnector duty is different from automatic circuit-breaker interruption.
